An international distribution company of containers has operated a 6-million unit capacity warehouse in Manila to service customers between the Asian continent and the North American continent for the past four years.
Liann Able, VP of logistics, sent the quarterly time series, which are the number of units in thousands serviced through the warehouse, to three of her analysts and asked them to bring forecasts to the next planning meeting for discussion. Liann convened the meeting and asked each analyst to report.
